HP Pavilion 15ab 268 Ubuntu Compatibility?

Hm. That looks quite similar to the HP Star Wars Edition notebook I'm ruing Ubuntu 16.04 on. This one's basically an HP Pavilion 15 with a bunch of Star Wars design and stuff added to it, but Intel I5, 6 GB RAM, 1 TB hard drive. Can't comment about the Linux/Windows dual-boot part because I wiped Windows, re-partitioned, and installed Xenial. I don't do Windows anymore. I got an excellent discount, less than half of what I'm seeing it going for elsewhere.

The one thing, everything on the screen was smaller than normal, had to adjust everything up. Other than that, it took to Ubuntu 16.04 quite well. Not sure if any of this helps you at all. I've had great luck with HP notebooks and Linux, though.
